Much of what we know about what asbestos companies understood, and when, comes from documents that surfaced in litigation and research archives. This category gathers those records and explains what each one shows.
The Sumner Simpson Papers, a cache of 1930s and 1940s correspondence, are among the most cited, because they suggest manufacturers discussed the health risks and the press coverage they wanted to avoid. The Gardner Letter and the related Vandiver Brown communications sit alongside them. Other entries document the products themselves, like Zonolite and Zonolite Attic Insulation, the vermiculite insulation contaminated with amphibole asbestos from Libby, Montana.
You'll also find technical and regulatory records here, from the CIB 62 industry bulletin to protective gear like the H-60 and H-64 masks. Together they form the paper trail that helps establish what a company knew and whether it warned the workers it exposed. Every term below links to a full plain-language definition.
